Is there a specific reason to not have a pharo vm build with subpixel rendering for non-US use? Stephan

Why do you think there are different builds?
Shouldn't there be? EU has higher standards for software patents, so there are no ClearType patents in EU afaik. Stephan

Why you think there's something in VM that blocking it? Or, if you speaking about Athens, i tried multiple times to 'fix' the problem and force Cairo to render fonts with subpixel quality.. no luck :( And Freetype package has own subpixel renderer implementation (in smalltalk , just FYI look at the code of applying a gamma-filter So, if you think you can do better, and feel adventurous, you can start from FreeTypeGlyphRenderer and improve it.. I had impulses, once before to clean it up and 1-st, understand what is going on 2-nd see how this can be improved. But you can look at this code, and let me know if it violates patent(s) or not :) Stephan

Maybe all the patents are expired? http://www.freetype.org/patents.html
